Solution
1. Preparation
  • Gather necessary tools and materials.
  • Ensure the vehicle is parked on a flat surface and the engine is turned off.
  • Disconnect the battery to avoid electrical hazards.
2. Check Refrigerant Levels
  • Connect a refrigerant gauge to the low-pressure service port.
  • If levels are low, perform a leak test using a dye or electronic leak detector.
  • If a leak is found, repair the source of the leak and proceed to recharge the system.
3. Replace or Recharge AC System
  • If refrigerant is low, use the correct type of refrigerant (usually R-134a for a 2018 Camry).
  • Follow the manufacturer’s instructions for recharging the system, ensuring not to overfill.
  • If the compressor is faulty, replace it by removing the old compressor, securing the new one, and ensuring proper electrical connections.
4. Inspect and Replace Cabin Air Filter
  • Locate the cabin air filter, usually behind the glove compartment.
  • Remove the filter housing cover and extract the old filter.
  • Replace with a new, clean cabin air filter ensuring proper airflow direction.
5. Test AC System
  • Reconnect the battery and start the vehicle.
  • Set the AC to the maximum cool setting and monitor system performance for cold air.
